In the drawingseFignre 1 is a side elevation showingthe rake sect-ions arranged on a. common axis or shaft support and in working position Fig. 2 is an end view of the cylinder; .Fig. 3 is a detail view showing means for adjusting or changing the' position of the eccentrics and the effect of such adjustment uponthe rake. arms and rake teeth; Fig. l is a detail side elevation showng the association of-the eccentric adjusting means with the eccentrics and an arched stop plate with which the adjusting lever is adapted to be connected at different points; Fig. 5 is a side elevation of the same matter that is shown in Fig. 4:; Fig. 6 is a detail view of the eccentric; Fig.7 is a detail plan view of the same subject matter as shown in Figs. at and 5. Fig. 8 is a perspective view showing the rake in proper working position relative to the framework of the machine.

Referring to the figures, 12 refers to frame portions of the machine, only fragmentary parts being shown for the purpose of indieating the relative position of the cylinder to the frame.

13 is a rake cylinder shaftdisposed angularly with relation to the frame, a driving connection therefor being shown at the left of Fig. 1. Bake sections 1e, 15,16 and 17 are fixed upon the common shaft 13 and are rotated thereby, in'the operation of the machine. Each rake section is formed of side frame parts or spiders having a central hub portion 7, fixedly mounted on the shaft and from which extend radial armsas 18 for section 1, 19 for section 2, 20 for sections 3 and 21 for section 4. The radial arms of each section are arranged in parallel relation both longitudinally andveftically but the arms of the separate sectionsiarelarranged each at a different-angle or staggered with the object andpur-pose of supporting of the different sections is best illustrated in Figs. 2 and 8.7 In Fi-g. 2 numerals 1, 2 3 1':

and i refer to the arms of the sections-l,

3 and l as they appeanin Fig. 1, and 2' also shows the relative positions of therake forks.

- The outer ends of the radial arms of each section are perforated and each set of arms of each section which lie in the same plane are connected by a rake head or bar as 22, with the ends of said bar bearing through the perforations in the arms at the sides of the sections. Rake teeth 23 are arranged in series andsuitably secured to: bars 22.

Wl1ile I have shown four rake sections,

each carrying three rake fork bars but in construction I may use only two rake sectlons and furthermore, each rake section may be made up of bars or arms adapted;

to carry two rake fork-bars, the disclosure in the drawings merely'representi'ng one form of embodiment, of my invention.

For the purpose of maintaining the rake heads 22in a permanent position so that the teeth will point continuously in a given direction that they may be set to occupy, I provide the eccentrics 2a fixed to eccentric hubs 24*, said eccentrics being adapted to embrace shaft 13, there being one provided between rake sections 1 and 2, and one between sections 3 and. 4. The eccentrics are constructed so that they are each adapted to. be embraced by two separate eccentric sheaves or rings, said'eccentric rings being indicated as 25 and each being providedwith three radial arms as 26, each arm provided with a perforation in the outer end thereof; 'The rake heads 22 orv the ends thereof adjacent the arms of the'eccentric 9.

rings 25, are extended beyond the supporting rake arms and bent intothe form of a crankarm and are adapted'to be entered in the perforations in the extremities'of the 'eccentric ring arms to maintain-a pivotal or turning relation therewith. The eccentrics 21 being loose upon shaft '13, it is necessary that they shall be supported in a permanent position, and to accomplish this fixing of the eccentrics, the levers 27 and arms .30

are provided, which are secured to the eccentrics, and-extending in an u'pward direc-' tion are adapted to be connected with per fora'ted arched plate or stop bar 28 by means -of stop pins 29, which plate or bar may be suitably secured to the frame work of the machine .at-a point above shaft 13 and in a parallel relation with the sides of the secsubjected so supported.

tions, one bemg provided between sections The eccentrics 24 may be set in any de-' sired position for the purpose of changing -the 'direction. of pointing of the rake teeth 23 (see Fig. 3)'by simply removlng pm 29 and shifting the eccentric about its axle sup port 13 and fixing it in connection with suitable perforations provided in bar 28 into the desired position. F urthermore, the eccentric may be shifted at will of'the'operator so as to throw the raketeeth to an extreme incline rearward of the direction of travel of the machine in transportation so that they will be out of the way when the machine is being transported. I have shown means for only one .a'djustment but obviously the plate 28 may be provided with any number of adjusting perforations. The

movement of eccentrics 2% will change the position of eccentric ring-arms 26 with relatlon to the centers of support for the rake heads 22, thereby moving the crank arms 23, which movement being imparted to rake heads 22 will change the direction of bearing or pointing of rake teeth 23.

, In the operation of the machine, as shaft 13 is turned, the rake sections will be revolved therewith, and as. the eccentric arms with the ends of the rake heads the cocentric rings 25 willbe carried about the eccentrics 24 and in. such movement the eccentricring arms 26' will be moved to and from the rake cylinder shaft 13,- thereby constantly changing their position relative to the centers of supportof rake heads 22, which will eflect a constant maintenance-of the rake teeth in a permanent; direction of pointing after the eccentrics have been fixed inanygiven position.

In carrying out my invention, the rake sections may be built as shown'inthe drawings, each with a taper converging gradually from the terminal end of the rake section at the delivery end .of the cylinder to the end of-the cylinder occupying the most advanced position. In suchformation, necessary lengths so that their outer the same horizontal plane when: raking ends will lie in and .26 .are connected through crank arms 23 it will be to-step the teeth at differentit will also be. necessary to inchne-shaft l3v so that as the sections are-revolved,therake teeth will meet the surface of the ground m a uniform, horizontal lane.- The rake secmade of uniform tions, however, may

on the inclined shaft,

diameter supported and in such case it will be necessary to;

gradually. lengthen the rake teeth progressively "from section 1 --to 4. However, the principle of operation of the machine is not change in thus carrying the construction of the rake sections.

In the drawings I have support for shaft 13 comprising a depend ing lug 31 connected with a frame bar 32 shown a center and likewise haveshown arched plates 28 integrally united 'with frame bars-33, but

any

machine that may desired. 1
